Soybean growers begin each season with the hope of fuller
pods and higher yields. Unfortunately, even if they expend
all their energy toward achieving this goal, their efforts may
be thwarted at the homestretch. Late-season environmental
stress may stand in the way of higher yields.
Helping soybeans
reach their true
yield potential
It is the Syngenta mission to enable soybeans to start
strong, grow strong and yield strong each season
so farmers can grow more soybeans. With the added
physiological benefits of Quadris Top® SB fungicide,
soybean plants are better equipped to reach their full
genetic yield potential. This high-performing fungicide can
enable fields to pass the finish line and yield strong.
Quadris Top SB: The fungicide of choice
• Offers physiological benefits and boosts yields an
average of 4 to 8 bu/A on farm trials
• Impacts plant growth to produce larger beans,
fuller pods and improved pod retention for better soybean
harvests
• Combines two active ingredients to deliver effective
disease control and resistance management
• Shows yield advantages by offering both preventive
and curative disease control
• Tank mixes with Endigo® ZC insecticide to target
yield-robbing insects, and is proven to enhance yields
and provide growers with consistent returns

Optimize soybean yield potential
The key to improving yield requires crop care and
maintenance throughout the season, but these considerations
become especially important as harvest draws near. During
the summer months, or around the R3 growth stage,
growers may want to consider applying Quadris Top SB for
disease control, especially against strobilurin-resistant frogeye
leaf spot, and also to minimize effects from adverse weather
and environmental stresses. Quadris Top SB increases
yield and maximizes return on investment by enhancing
physiological benefits in the plant under these conditions.
roots can’t extend deeper to reach the water located
farther underground. Quadris Top SB promotes root
growth so that roots grow deep enough to support the
plant. Quadris Top SB also helps manage periods of
low-moisture stress and high temperatures by reducing
transpiration. To cope with dry conditions, reduced
transpiration enables soybeans to conserve water.
Proof in the numbers: Quadris Top SB
takes the top spot
• Production of larger beans, fuller pods and
increased pod retention: Quadris Top SB enables
plants to stay greener longer, which in turn allows
plants to utilize the sun’s energy longer. This provides a
larger energy supply for prolonged photosynthesis and
extended pod development leading to larger beans, fuller
pods and increased pod retention, all of which increase
yield potential.
In a 2013 soybean fungicide trial comparing Quadris Top SB
to competitor fungicide treatments and untreated soybeans,
Quadris Top SB yielded 65 bu/A, outperforming other
fungicide treatments by at least 6 bu/A.
In the photo below, the plot on the left was treated with a
tank mix of Quadris Top SB and Endigo ZC, and yielded
68.6 bu/A. The plot on the right was untreated and yielded
48.4 bu/A. (Mt. Jackson, Va.)

Enhanced physiological responses
Quadris Top SB helps manage periods of environmental
stress – both too much or too little water, and high
temperatures. The following physiological benefits allow
soybeans to yield strong:
• Development of larger and stronger roots:
Quadris Top SB helps plants develop a more vigorous
root system to support increased plant growth. These
larger, stronger roots are better equipped for water
and nutrient uptake and translocation, even under
unfavorable growing conditions such as too much or too
little water. If conditions at planting are wet, roots tend
to grow shallower because there they can easily absorb
water from near the surface of the soil. This can be a
problem if the soil dries out later in the season and the

The chart below shows the yield benefit of using
Quadris Top SB compared to untreated soybeans.
Quadris Top SB not only provides outstanding physiological
benefits, but it also reduces the effects of unwanted disease
pressures in a field. Quadris Top SB is a robust combination
of two industry-leading chemistries to create one of the most
powerful fungicides on the market. With multiple modes of
action, the preventive and curative activity of Quadris Top SB
provides broad-spectrum disease control, including
protection against strobilurin-resistant frogeye leaf spot.

• Aerial blight (Rhizoctonia solani)
• Alternaria leaf spot (Alternaria spp.)
• Anthracnose (Colletotrichum truncatum)
• Asian soybean rust (Phakopsora spp.)
• Brown spot (Septoria glycines)
• Cercospora blight and leaf spot (Cercospora kikuchii)
• Frogeye leaf spot (Cercospora sojina), including
strobilurin-resistant strains
• Pod and stem leaf blight (Diaporthe phaseolorum)
• Powdery mildew (Microsphaera diffusa)
